Description

Closing device
The invention relates to a device of lock with an electronically coded key, according to preamble of claim 1.
A closing device of this class is known by DE 195 17 728 A1. In this one, the closing cylinder it carries a cylinder bag in which the actuator is housed made as an electric motor. The channel for the key is open in the direction towards the enveloping surface of the cylinder core. The closing organ is made as a stirrup that with its two ends enters two housings of the envelope surface of the cylinder core, on either side of the cylinder channel open, in the axial zone of the cylinder core, equipped with mechanical skewers. The actuator arranged in the cylinder bag and made as an electric motor has a shaft with two opposite cams each other that in the closing pressure they attack in the stirrup or in the cylinder housing
The known locking device, with a key with electronic-mechanical coding, it has credited broadly. However it is necessary to replace all The complete cylinder lock. Also you can also only transform for this closing device the locks of cylinder carrying cylinder bag.
From DE 42 07 161 A1 a known closing device with a closing cylinder in which it is provided an additional electronic lock in the form of a cover additional. It contains a hood that rotates along with the core of the cylinder.
From DE 297 03 063 U1 a known additional electromagnetic lock for the cylinder core, which attacks in accommodations located on the periphery of the nucleus of the cylinder.
Also, in DE 196 53 113 A1 patent describes the realization of an annular coil that serves as a antenna for data transmission, in a cylinder lock With additional electronic insurance.
The aim of the invention is to be able to transform virtually all cylinder locks, without have to replace them, in a closing device of this class with electronic coding, in particular mechanical electronics
This is achieved, according to the invention, with the closing device characterized in claim 1. Convenient embodiments are reproduced in the subclaims of the invention.
The safety of the closing cylinders, to Often, it leaves enough to be desired. So, for example, you can undo by screwing a screw into the key channel or using other undo tools. To better protect the closing cylinders, these are provided, therefore with a called cylinder shield, which consists of an armored body massif that is placed around the closing cylinder, and in which a solid armored disc with a slot for the key step The armored body and the armored disk are of a hard steel, for example, a nickel chrome steel.
The invention is based on the idea of controlling, by electronic key coding, access to the channel for the key in the cylinder core with the armored disc. For in accordance with the invention, the closing cylinder is provided with one of these cylinder shields. The shield of cylinder contains, inside the armored body, the actuator as well as to the closing organ actuated by it, precisely in a arrangement such that in the locked position it adjusts with the disc armored preventing its rotation and that in its open position leaves free the armored disk.
This means that as in a shield of conventional cylinder, the armored disc prevents access to the channel for the key in the cylinder core, using a screw or another similar unlocking tool. But at the same time the armored disc fulfills the function of allowing only the rotation of the cylinder core if a correctly coded key is used electronically
The closure member preferably fits in a recess in the perimeter of the armored disk. In its closed position It is preferably subjected to the force of a spring. The force to fit the closing member in the locked position, it is that is, in the recess located in the perimeter of the armored disc, the therefore supplies the spring. The decoupling of the organ from closing of the recess in the armored disk, that is, the authorization of armored disc rotation, takes place due to manual force applied by turning the key inserted in the core of the cylinder.
To facilitate decoupling, you can provide surfaces in the closing element or in the housing of sliding or rolling bodies, for example a ball or a roller. In this way the closing body opposes a force of large cut against the violent turn of the armored disc, in the lock position On the other hand, by turning the core of the cylinder with the key, the locking member slides or rolls out of the housing and then along the armored perimeter.
The actuator can be for example an electromagnet. However, it will preferably consist of an electric motor, that moves an element that in the locked position adjusts preferably with both the closing body and the body armored. The actuator is therefore bistable. This means that the electric motor is without current both in the position of lock as in the armored disc release position.
The element that is moved by the electric motor it can be the nut of an endless transmission, which is guided movable in the armored body within which it adjusts a thread located on the motor shaft. There is also the possibility of make the element, for example, eccentrically on the Camshaft with two opposite cams, where in the position of armored disc lock the two cams rest on the organ of closure or on the armored body.
Since the displacement of the closure organ to the blocking position takes place by means of the quoted spring, while the force to move the closing organ to the release position is applied manually when turning the core of the cylinder, you can use an engine of very small dimensions, which It can be housed in the armored body taking up little space.
Its energy consumption is also very small. For the power supply of the actuator or motor, it can be provided a battery that can be placed in the door. But preferably the power supply is integrated into of the cylinder shield, for example, a button battery provided in the armored body. You can also be arranged in the armored body the code evaluator.
The essential advantage of the invention lies in so that the closing cylinder already existing in the door is you can keep absolutely unchanged, since it is only done It must be placed on the closing cylinder, on the side a security risk, that is, on the outside, by fixing it to the same, the armor of the cylinder with the closing element and the actuator as well as possibly the electronic code evaluator and the power supply unit.
The cylinder shield may be sized in such a way that it fits virtually any cylinder of closing. In this way it is independent of the brand. This it means that according to the invention it can be modified to virtually any closing cylinder, as per example a cylinder with euro profile, a round cylinder or a oval cylinder, with an extremely simple assembly.
It is understood that according to the invention it is possible to modify both the cylinder locks that have a single cylinder core like double cylinder locks with Two cylinder cores In the latter case, it will be provided with cylinder shield object of the invention the cylinder core located on the side that poses a security risk, that is for example, on the outer face of a door.
In that case, the side cylinder core The interior of the door can only be opened by mechanical key coding.
According to the invention, the key can have exclusively an electronic coding. But as usual are the conventional closing cylinders with mechanical pins those that are provided with the shield of the cylinder object of the invention, electronic coding usually only supposes an additional code that complements the mechanical code of the key.
The electronic code transmitter on the key It is preferably formed by a transponder and the evaluator electronic codes, in the cylinder shield, preferably by a transponder reader device. For this the key has preferably a ferrite antenna. If it is done as a key rotating, two ferrite antennas are planned, one on one side and another on the other side of the key disk. The disposition of ferrite antennas on the armored body and on the key has been chosen in such a way that, being the key inserted in the cylinder of closure, there is only a narrow gap between the antenna armored body ferrite and the key ferrite antenna, from so that during transmission there are only losses of Very low energy.
The transponder reader device comprises a microprocessor and nonvolatile memory. In general it is also provided a clock for the date and time function you use a quartz oscillator as a time base. The actuator is activated directly by the microprocessor.
When the key is removed, that is when the ferrite antenna of the key moves away from the antenna of ferrite that is in the armored body, the closing body displaces to the actuator to the closed position. Turning the key inserted in the closing cylinder, the ferrite antenna of the key is also moves away from the ferrite antenna in the armored body This means that if no other measures are taken In addition, the actuator would be actuated by rotating the cylinder of closure and would certainly try to move the closure organ to the closing position
To avoid this, that is to leave the idle actuator when turning the key, a rotation sensor can be provided, by example a piezo element or a switch that determines the position angle of armored disc or cylinder core. Since at rotate the armored disk or the cylinder core the closing member is in the release position, the switch will be preferably performed in such a way that it is operated by the closing organ when it is in the position of release.
The concepts of "closing cylinder", "cylinder housing", "cylinder core", "channel for the key "and" key "must be interpreted in a sense broad according to the invention. For example, the invention encompasses also draggers that have a rotating support within a housing, if the carrier has a housing, for example, a polygonal inner hole, into which a tool as a key, for example polygonal. Of the In the same way, the armored body can also be formed by a piece of hardware.
The following are described in more detail at example title various embodiments of the closure device object of the invention, using the drawing. In this show:
Figure 1 a perspective view of a shield of the cylinder according to an embodiment of the invention;
Figure 2 a longitudinal section through a closing cylinder with the cylinder shield according to figure 1, in the closed position;
Figure 3 a section along the line III-III of Figure 2;
Figure 4 a longitudinal section through another embodiment, in the release position;
Figure 5 a section along the line V-V of Figure 4;
Figure 6 a longitudinal section through another embodiment, in locked position;
Figure 7 a section along the line VII-VII of Figure 6, and
Figure 8 a longitudinal section through another embodiment, in the closed position.
According to figure 1, a shield of cylinder 1 consists of an armored body 2 with a front wall 3 and a peripheral wall 4. In the front wall 3 it is housed inside a hole a rotating armored disk 6, which has a groove for the passage of the key 7. The armored body 2 and the armored disk 3 are of a steel several millimeters thick, for example, of nickel chrome steel.
A lock is shown in figure 2 double cylinder 10 with two cylinder housing halves 8, 9, in which two cylinder cores 11, 12 are housed rotating Each cylinder housing half 8, 9 is provided with a cylinder bag 13, 14. Between the housing halves of the cylinder 8, 9 is provided a housing for a closing pallet 16, which is connected without rotation with the cylinder cores 11, 12 through a coupling that is not represented. Hole 18 It is used to fix the double cylinder lock 10 with a screw a door.
About half of cylinder housing 8 arranged, for example, by the outer face of the door goes placed the cylinder shield 1, so that the front face and the perimeter of the half of the cylinder housing 8 remain covered by the cylinder shield 1. The cylinder shield 1 it is fixed to the middle of the cylinder housing 8, such that the passage groove for the key 7 is aligned with the channel for the cylinder core key (which is not operated). The disc armored carries an annular flange 15, which is housed in a slot annular 17 on the inner face of the front wall 3 of the body armored 2, preventing it from being removed.
In the peripheral wall 4 of the shield of the cylinder 1 and from the bottom face away from the armored disk 6 is arranged as an actuator an electric motor 19 in a corresponding Longitudinal housing on the inner face. On the front wall 3 of the cylinder 1 shield and in a corresponding guide located in the inner face is radially movable in one and the other felt a closing organ 21.
The closing member 21 prevents, in its position of closure shown in figures 2 and 3, the armored disk rotation 6, while in the release position represented in the Figure 5 allows armored disk 6 to rotate. By locking the rotation of the armored disk 6 according to figures 2 and 3 prevents same time the rotation of the core of the cylinder 11 by means of the key 22, whereby lock 10 is locked, while when armored disk 6 is released to rotate according to the Figures 4 and 5, the cylinder core 11 can be rotated and so both the lock can be opened, assuming the recesses (no represented) and other mechanical encodings of the key 22 move the skewers (not shown) of the cylinder lock 10 to the release position.
The closing organ 21 is realized as a stirrup with two ends 24, 25 that fit into two housings 26, 27 on the perimeter of the armored disk 6 on either side of the key slot 7, for which the closing element or stirrup 21 is forced by springs 28, 29 to the position of coupling (figure 3).
The shaft 31 of the electric motor 19 carries a thread that fits into a nut 33 that is housed movable in the corresponding longitudinal housing 34 arranged on the face inside the shield of the cylinder 1, such that in the closing position according to figures 2 and 3 is located between the closure member or stirrup 21 and peripheral wall 4 of the cylinder 1 shield while in the release position according to figures 4 and 5 it is displaced towards the electric motor 19 such that the closing member or stirrup 21 can be move radially away from armored disk 6 overcoming the spring force 28, 29.
This means that in the position of release shown in figures 4 and 5, by turning the key 28 The ends 24 are pushed into the core of the cylinder 11, 25 of stirrup 21 outside of housings 26, 27 of the disk armored 6, overcoming the force of the springs 28, 29, thereby the cylinder core 11 can rotate freely.
On the front wall 8 of the armored body 2 is arranged a rotation sensor 35 that captures the position of the organ of close 21 and thus prevent the electric motor from being operated 11 after releasing armored disk 6, when rotating the disc armored 6.
According to figures 1 to 3, on the wall front 3 of the armored body 2 and in a corresponding hole a ferrite antenna 36 is arranged. The antenna 36 is connected to an electronic code evaluator 37, for example a device transponder reader, which is arranged in a housing in the inner side of the peripheral wall 4 of the armored body 2. The power supply system 38 consists of a battery button that is located in a housing on the inner face of the peripheral wall 4 of the cylinder body 2, on the opposite side to the code evaluator 37.
The key 22 carries in the fist of the key 40 a ferrite antenna 41 that is connected to an electronic module 42, which contains the data carrier or code generator. Module 42 It can be done as a transponder.
The embodiment according to figures 4 and 5 differs from that of figures 2 and 3 essentially because the code evaluator and power supply unit are not arranged in the armor of the cylinder 1 but, for example, in the Inner face of the door.
In the embodiment according to figures 6 and 7, the antenna that is connected to the code evaluator 37 is made as annular antenna 43, arranged on the front wall 3 of the armored body 2, concentric around the hole for the shielded disk 2. The annular antenna 43 has greater power, ie which in addition to having greater reach offers the advantage of greater speed in data transmission and, therefore, times of shorter opening. In this embodiment you can also eventually give up the rotation sensor 35.
In the embodiment according to figure 8, the ferrite antenna 44 is arranged in an inner housing in the front wall 3, ie displaced inwards and so So much is not accessible from the outside. The key 22 is made as a reversible key. According to this, they are planned ferrite antennas 45, 46 in the area of each face close to the stem of the key, precisely in that area of the key shank inside the armored disk 6 when the key 22 is inserted in the channel for the key of the cylinder core 11.
